Two lenses, a lens of 12.5cm focal length and a minus lens of unknown power, are mounted coaxially and 8 cm apart. The system is afocal, that is light entering the system parallel at one side emerges parallel at the other. If a stop 15mm in diameter is placed halfway between the lenses: 1) Where is the entrance pupil? 2) Where is the exit pupil? 3) What are their diameters?; Keywords and concept; Keywords and concept; Keywords and concept;3. Wave aberration: The degree of departure from true sphericity,that is, the distance between the ideal reference sphere and the actual, distorted wavefront, measured along the radius of the reference sphere.; Homework; Homework; Homework Answer;small. If this is so, the sines of these angles can be set equal to the angles themselves( in radians). In fact, the angles are larger, and if we use exact ray tracing, this can no longer be done. The sine of an angle must the
